Full TextAbstract
Using the compatibility of the DBI and the Chern-Simons actions with the T-duality transformations, we extend the curvature corrections to these actions to include the quadratic B-field couplings at order O( alpha ^2) . We then use the compatibility of the couplings on D$_3$-brane with the S-duality to find the nonlinear RR couplings at order O( alpha ^2) . Using the modular functions that appear in the curvature corrections, we then write the results in SL(2,Z) invariant form.
